Billy McGroarty
I recently graduated from Clarkstown High School South, and since August 2021, I have been working at Clarkstown Coin & Jewelry under the guidance of Seth, Pete, and John. Over the years, l've built a solid foundation in understanding coin values, numismatic history, and the joy of collecting. l've also developed an appreciation for the artistry of jewelry and gained insight into the business side of the industry.
Working in this environment has taught me more than product knowledge — it's shown me the importance of customer engagement, active listening, and learning from others' stories. I genuinely enjoy speaking with customers, discovering their perspectives, and expanding my own world 'through these interactions.
Looking ahead, I'm excited to take the life skills and experiences l've gained into the next chapter: studying biology at Norwich University, with the long-term goal of joining the FBI.

I have been frequenting the shop since 2016, when I first became interested in numismatics. Since working here, I have enjoyed learning the business aspect of coins, jewelry, and precious metals. Getting to know and interacting with the customers is also a highlight. When I’m not at school, you can catch me at a number of coin shows across the country. Going forward, I plan to further my education, and continue to gain experience, so eventually I can work full time doing what I love.
